As a jumper training pilot for the SDSU Skydiving team during the fall and spring of '72,'73 and '74 I dropped 384 from a gutless, easily overloaded 1961 Skyhawk, 145hp. Right door and rear seats removed. One was on the floor beside me, two in the back. Before the first flight I was told to always carry a very sharp hunting knife within reach to cut the static line should it tangle and not open the student's chute. All jumps were solo static line in those days until you could pull your own. It was not possible to land with him hanging down there, so I was prepared to cut his line. He could still open his reserve chute. Directions to the jumpers were to get feet out the door with hands moving from door posts to strut, left foot on gear step then pull into position with the right foot on the wheel while I held the brakes at 80 mph into the wind. Lean forward with both hands on the strut, then kick back with both feet and push off the strut hard and arch spread eagled. Never lost one, no one ever fell and I never cut one off the static line but one broke a few bones on landing once. As for using my own plane I would not. Safety trumps every consideration you can have for the upholstery and interior and the paint on loading and getting out. It was abusive to the plane. Even a four place is cramped with you both wearing a chute and it flies cockeyed with the door open. Even with signed waivers, I wasn't smart enough at 19 to even think about liability issues and I doubt they were either.
